For the oldstable distribution (wheezy), this problem has been fixed in version 0.6.4-1+deb7u2. This update also fixes CVE-2015-7801, which was originally targeted for a wheezy point update.

For the stable distribution (jessie), this problem has been fixed in version 0.7.5-1+deb8u1.

For the unstable distribution (sid), this problem will be fixed soon.

We recommend that you upgrade your optipng packages.");
